Unable to install pybgs with opencv-python pip

[Shubham Jaiswal]

I have installed opencv-python using pip command, but while trying to install pybgs using pip, I get the following error which says :

By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "OpenCV", but
CMake did not find one.

  Could not find a package configuration file provided by "OpenCV" with any
  of the following names:

    OpenCVConfig.cmake
    opencv-config.cmake

  Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set
  "OpenCV_DIR" to a directory containing one of the above files.  If "OpenCV"
  provides a separate development package or SDK, be sure it has been
  installed.


-- Configuring incomplete, errors occurred!
See also "/tmp/pip-install-8eq0c4r_/pybgs/build/temp.linux-x86_64-3.5/CMakeFiles/CMakeOutput.log".
error: command 'cmake' failed with exit status 1

Does the above essentially mean that, opencv has to be build for using bgslibrary and a pip install of the same will not work?

Hi @shubham162019 ,
Yes, unfortunately you need to install opencv lib.
The opencv-python package is limited to python scripts only,
As the core of bgslibrary is on C++, and the pybgs is just a wrapper around it, so when you do pip install pybgs it will download the C++ source code and compile the python wrapper locally.
